In addition to a range of paintings, sculptures and works on paper, the selection in Artstor includes substantial materials from the museum's Artists Archives, which consist of the work of eight prominent American photographers of the twentieth century: Clara Sipprell, Erwin E. Smith, Karl Struss, Laura Gilpin, Nell Dorr, Eliot Porter, Carlotta Corpron, and Helen Post. Other highlights include Mexican War daguerreotypes and works by Alfred Stieglitz, Edward Curtis, Eadweard Muybridge, David Octavius Hill, and Southworth & Hawes.

The Amon Carter Museum of American Art was established through the generosity of Amon G. Carter Sr. (1879–1955) to house his collection of paintings and sculpture by Frederic Remington and Charles M. Russell, and to further the appreciation of American art both through acquisitions and a commitment to education. The museum also holds more than 40,000 photographic prints, making it a major repository of American photography. Throughout its history, the Amon Carter Research Library has acquired illustrated books to support the museum's collection.
